  This method returns a performanceTuning object on the model. This can be null if the query has not been set. User can create a new PerformanceTuning object and set it on the model. The returned object may be a different than the set object, in case of it being set on multiple models. The model checks for an existence of model (property) on the passed in object and if there is one, it makes a copy of the passed in object and sets it on this model. In other words there is one to one relationship between model and the performance tuning object.

  Specified by:
    `getPerformanceTuning` in interface `OLAPDataSetInterface`
  Returns:
    performanceTuning object
  Throws:
    `OLAPException`

### setPerformanceTuning

    public void setPerformanceTuning(PerformanceTuning performanceTuning)
                              throws OLAPException

  Set the PerformanceTuning Object on this model. Nothing will happen if the object is null. Since each instance of model has its own performance tuning, if this object is derived from another model or it is already set on another model, a copy of the perfroamnceTuning object will be made before setting it on this model. In other words, a get may not return the same object as the set.

  Specified by:
    `setPerformanceTuning` in interface `OLAPDataSetInterface`
  Parameters:
    `perfromanceTuning` - An Object that has performanceTuning properties set on it. Null will not have any effect.
  Throws:
    `OLAPException`

  Description copied from interface: `OLAPDataSetInterface`
  This method returns an instance of the MetadataInterface which defines all of the Cubes' metadata on the OLAP Server to which the model is connected. Implementations which do not support this MetadataInterface should return null.

  Specified by:
    `getDatabaseMetadata` in interface `OLAPDataSetInterface`
  Returns:
    metadata An instance of the MetadataInterface that shares the same connection as the Data Model
  Throws:
    `OLAPException` - If a database error occurs

### cancelQuery
